Focus on running existing code in a modern container, instead of emulating an old environment to the dumbest details. Fully open source!
vJCRE is a vritual Java Card Runtime Environment that allows to run Java code targeting the smart card platform inside a standard desktop Java virtual machine. Ideal for fast development, testing or experimentation.
- Easy interfacing with any APDU-like interface:
CommandAPDU
from javax.smartcardio- Generic
byte[]
exchange, like Android Host Card Emulation - JavaCard 2.2.2+, usage of Extended APDU encouraged
- HostApduService proxy for Android
- Includes all packages with essential interfaces and abstract classes up to JavaCard v3.0.4:
javacard.framework.*
javacard.security.*
javacardx.apdu.*
javacardx.crypto.*
- Simple, thin and modular codebase to the finest extent possible.
- Minimal one-liner pollution in
javacard*.*
. The only allowed import is from pro.javacard.vre.*; - No Javadoc or license for API specification. Go read the original API docs. (hint)
- Implements necessary JCSystem and APDU, cryptography provided either by standard JCE or BouncyCastle.
- Applet management interface, not unlike GlobalPlatform
- No support for:
- Transactions
- RMI
- Services
- Logical channels
- Future versions
- More algorithms, including JavaCard 3.0.X features
- Multiple independent VJCRE instances in a single VM
- Saving and loading VM instances (real "virtual cards")
- Works great with the rest of the open source smart card stack.
- Made in Estonia
import pro.javacard.*;
VRE vre = VRE.getInstance();
AID aid = new AID(FakeEstEIDApplet.aid);
vre.load(FakeEstEIDApplet.class, aid); // Load the applet with the specified AID
vre.install(aid, default); // Make a default selected instance of the applet with same AID
TerminalFactory tf = TerminalFactory.getInstance("PC/SC", vre, new VJCREProvider());
CardTerminals terms = tf.terminals();
// Now use javax.smartcardio as you would do when talking to a real smart card
Version 0.1 will be released early March 2014 together with FakeEstEID Android version. Until that time feel free to look around in the repository.
